🔤 Base64 Encoder / Decoder
Convert text to Base64 encoding or decode Base64 strings back to readable text. Supports Unicode characters via UTF-8.
What is Base64?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used when you need to encode binary data that needs to be stored and transferred over media designed for textual data.
Common Uses
- Embedding images or files in HTML/CSS as data URIs
- Encoding email attachments (MIME)
- Storing binary data in JSON or XML
- Encoding authentication credentials in HTTP headers
Note: Base64 is encoding, not encryption. It does not provide any security — it's simply a way to represent binary data as text. Anyone can decode Base64 back to its original form.
